APC by Schneider Electric AP8881REDX667 Metered Zero-U Rack PDU
Overview
The AP8881REDX667 is APC by Schneider Electric's Rack PDU 2G Metered Zero-U unit rated at 11kW/230V, delivering 36 IEC C13 outlets and 6 IEC C19 outlets in a vertical zero-U form factor designed to mount inside a rack cabinet without consuming any rack unit space. This makes it a practical choice for high-density rack environments — data centers, security head-end rooms, and enterprise network closets — where every rack unit is occupied by active equipment.
Zero-U mounting means the PDU installs along the vertical rail of the cabinet, preserving all 42U or 45U of usable rack space for servers, NVRs, switches, and other active devices. The metered variant provides per-unit input power measurement, giving infrastructure and facilities teams visibility into actual load before circuits approach capacity — a meaningful operational advantage over basic non-metered strips.
With 11kW of total capacity at 230V, the AP8881REDX667 handles high-draw configurations: a mix of 1U servers, PoE switches, NVRs, and network appliances that together pull several kilowatts. The 36 C13 outlets cover standard IEC-cord equipment (1U servers, switches, storage), while the 6 C19 outlets accommodate higher-amperage loads such as blade chassis power supplies or dense storage arrays that draw beyond what a C13 circuit provides.
As part of the APC APC by Schneider Electric power distribution lineup, the AP8881REDX667 is compatible with APC's EcoStruxure and network management card ecosystem, supporting integration into centralized rack PDU management platforms for remote monitoring and outlet-level control where applicable.
Key Features
- 11kW / 230V Input Capacity: Handles dense rack configurations drawing multiple kilowatts — sized for mixed-load cabinets running NVRs, PoE switches, and servers simultaneously without tripping branch circuits.
- Zero-U Vertical Form Factor: Mounts inside the cabinet's vertical rail channel, consuming zero rack units — every U stays available for active devices. Critical in fully populated 42U/45U cabinets where space is exhausted.
- 36 IEC C13 + 6 IEC C19 Outlets: 42 total outlets serve both standard 1U server/switch loads (C13) and higher-amperage equipment like blade power supplies and dense storage arrays (C19) from a single PDU, reducing the number of distribution units per cabinet.
- Metered Input Monitoring: Real-time input power measurement lets facilities teams track actual load versus circuit capacity, catching overloads before a breaker trips and providing the data needed for accurate capacity planning across racks.
- 2G (Second Generation) Platform: APC's 2G PDU architecture supports integration with the APC network management card ecosystem for remote monitoring, alerting, and management — relevant in unmanned data center and security head-end deployments where on-site staff access is limited.
Integration and Compatibility
The AP8881REDX667 is designed for standard 600mm and 800mm wide rack cabinets from APC and third-party manufacturers. The IEC C13/C19 outlet configuration is broadly compatible with server, networking, and security equipment using standard IEC power cords. For environments running APC's UPS and power management infrastructure, the 2G platform supports connection to APC network management cards for centralized visibility. Consult APC's current compatibility matrix or your pre-sales engineering team for specific NMC models supported with this PDU.
For facilities deploying this unit alongside PoE network switches or high-density NVR stacks, verifying the total draw against the 11kW input rating before commissioning is recommended — particularly in mixed C13/C19 configurations where C19 loads can consume a disproportionate share of available capacity.
Frequently Asked Questions
Q: What is the outlet configuration on the AP8881REDX667?
A: The AP8881REDX667 provides 36 IEC C13 outlets and 6 IEC C19 outlets, for 42 total outlets at 230V.
Q: How does the Zero-U form factor work in a standard rack cabinet?
A: Zero-U PDUs mount vertically inside the rack cabinet's side channel or rear rail, occupying no horizontal rack unit space. This preserves all usable U-space for active equipment — servers, switches, NVRs — rather than consuming 1U or 2U for power distribution.
Q: What is the total power capacity of the AP8881REDX667?
A: The AP8881REDX667 is rated at 11kW at 230V input, suitable for high-density rack configurations with mixed server, networking, and security equipment loads.
Q: Is the AP8881REDX667 a metered or switched PDU?
A: It is a metered PDU. Metered units provide input power measurement for load monitoring and capacity planning. If per-outlet switching or outlet-level power control is required, a switched PDU variant would be the appropriate choice.
Q: What rack cabinet width is the AP8881REDX667 compatible with?
A: The AP8881REDX667 is designed for use in standard rack cabinets. Verify mounting rail compatibility with your specific cabinet model; APC's own NetShelter cabinets are the primary reference platform, and many third-party 600mm and 800mm cabinets are compatible.
The AP8881REDX667 is a unit I recommend specifically when a cabinet is already packed — the Zero-U vertical mount is the deciding factor. At 11kW/230V with 42 outlets (36 C13 + 6 C19), it handles the kind of mixed-load rack you see in a security operations head-end running several NVRs, a PoE switch stack, and edge servers, without giving up a single rack unit to power distribution.
Technical Highlights:
- 11kW/230V Capacity: Supports dense cabinet builds — at 230V you're drawing less current for the same wattage compared to 120V, which reduces cable heat and voltage drop across long PDU runs inside a rack.
- 36 C13 + 6 C19 Outlet Mix: The six C19 outlets are where this PDU earns its place in higher-draw configurations — blade chassis PSUs and dense storage controllers that need the heavier C19 circuit don't force you to a second PDU or an adapter chain.
- Metered Input Monitoring: Knowing your actual draw versus rated capacity is the difference between planned growth and an unexpected breaker trip at 2am. The metered 2G platform feeds this data to APC's network management infrastructure for ongoing visibility.
Deployment Considerations:
- Confirm your rack cabinet supports APC's Zero-U mounting rail before ordering — some third-party cabinets require an adapter bracket and APC's compatibility documentation should be consulted for your specific cabinet model.
- At 11kW, this PDU requires a dedicated 230V circuit rated appropriately for the load; do not daisy-chain or share the upstream circuit with other equipment without a verified load calculation.
Best positioned in high-density security or data infrastructure racks — specifically head-end rooms running 20+ NVRs or server blades where outlet count and zero rack-unit footprint both matter simultaneously.
